Frequently Asked Questions
How does JPG compression work?
Our tool uses MozJPEG, the same encoder used by major web services. It re-encodes your JPEG with optimized Huffman tables and quantization, achieving much smaller files with minimal quality loss.
What is MozJPEG?
MozJPEG is an improved JPEG encoder by Mozilla. It produces smaller files than standard JPEG encoders while maintaining the same visual quality.
Will I lose image quality?
At the default quality setting (80), the difference is imperceptible. You can adjust the quality slider to balance between file size and quality.
Can I compress multiple JPG files at once?
Yes! Drag and drop multiple files or select them all at once. All files are processed in your browser simultaneously.
